- Liquid Filters and Purifiers, which the following is a specification K This invention relates to filters and purifiers for water andli uid's; and it consists. of certain new. and nove combinations of filtering means and an electric current whereby the liquid is subjected to the influence of the current while passing through the filtering means, so that the particles ofsolid v matter of the liquid are caused to be attracted to each other andlare precipitated and their movement with the water-current checked by the said filtering means, and only the purified and filtered liquidis permitted to be drained ofi. These andother objects and details-of my invention will be'more fully described in the following specification and set forth in the'appended claims.

In the drawings accompanying thisspecification and forming a part thereof ike reference characters are used torefeto like parts. y Figure 1 isa front elevation ofmy improved filter. Fig. 2 is. a central vertical sectional view of same..- Fig;3 is a side view of thecircuit-closin valve. Fig. 4 is aside view of'one of the tering-cups.

The device shown in the drawings is a portable filter ada ted to be attachedto the s up- 'ly-cock for amily consumption, or it may 7 e usedon counters or tables in restaurants and the water supply pipe lead thereto. 1 The base 5=may-be a block of wood, hard rubber, or other material of compact and artistic design and'hav'ing acircular depressionfi in its upper face and recesses ,7 and 8 t0 accommodate the. faucet 9- of .ordinary construction and communicating, by means of'thepip e10,

with thechamber 11 within the-cylinder 12,

which i'or cleanliness and to exhibit ,thelinterior ofsame, may be made of glass or, other transparent substance. Y The ends of the. cylinder'12 are held'undercompression between.

two plates 13 and 14,a rubber or similargasket 15beinginterpo'sed between the .c linder and the plate 13,-which latter fits wit 'n the depression 6. The upper endof the cylinder.

tie-rods 18, uniting the plates 13 and 1.4, are properly adjusted. Beneath the plate 14 and between it andthe upper end 0 the cyl- OTRIC is also provided with a gasket 16, and these gaskets renderthe compartmentthoroughly 5 5' water-tight when the thumb-nuts 17 on the inder 12 is a circular block of non-conductive- 6o material 19, with a central screw-threaded hole to receive the member 20 of a pipecoupling 21. passes through an opening in the plate 14.

This coupling-section 20 also and a washer 22 is interposed,and when screwed down the coupling member 20 holds the parts 14 and 19 close together.v The upper end of pipe 10 has athimble 10*, which screws therein and by means-of the gasket 15 forms a close and water-tightconnection between the pipe and thechamber 11. The block 19 has around its under side near the outer edge a groove for the gasket 16, while about its center it has two depressions of varying depth 23 and 24, with vertical walls 7 5 Y which have inwardly-projecting radial pins 25 and 26, respectively.

Within thede ression 23 is adapted to fit the'upper end 0 a'cup 27 of thin non-corrosive material, preferably metal, and having at each side an angular slot 28, which, in conjunction with the pins 25, form bayonetjoints or means of securing the cup to the I block in.a suspended position. A series of perforations 29 surround the cup near its up per edge, and within the cup is a coil or cyl- Finder 30, of porous materialsuch as felt,

paper, or .cloththrough which the water passes {before leaving. the cup through the perfor tions 29. 1

Within the depression 24 is an identical cup 31, except that its dimensions are slightly greater; but it has the same bayonetjoint connectin means with the pins26, which hold it Within t e depression, audit also contains a porous coil 32. Instead of .using a bayonet- I joint coupling to secure the cups tothe block 19 it;is obvious that various meansmay be adoptedwhich may not be necessary to illustrate, and the cups may be inserted and held I00 in place by means of screw-threadsformed in their .upper ends ,'and similar. threadswill be cut in thewalls of the depressions 'to receive same. Perforationsi33 also'surround the up-.

per edge of the on .porous coil exten s above the line of theper.

. cups may also be used, such as wi1'e-gau-ze, to=

forations, so that water or other liquids entering the inner cup 27 through-the supply pipe 34 can only pass out of the perforations through the porous coil, andwith theouter The supply-pipe 34 is provided with an enlar erne'nt35 at its end, and the same is held within. the coupling 20 21, and the pipetmay also have a tap 3,6 to draw oflthe liquid before passing through the filter;

Through the block 19 from its outside edge to the wall of the depression 23 runs a wire or p1n3'7, whose innerend makes contact with the cup 27 and whoseouter end has bindingnuts 38 to attach the wire of an electric circuit.39. A similar pin 40 also passes into the block; and has its inner end terminating in a its outer end the lever 45, carrying at its lower end a lateral pin .46, insulated from the lever by the non-conductive bushing 47' and having the binding-nuts 48 to attach to-it the wire of the circuit 39. When the lever is swung soasto open the valve and permit of the passage of liquid into'the pipe 34, the pin. 46 comes in contact-with a stud 49, projectingfrom a conducting-disk 50'-on the side of the valve, and completes the electric circuit through the disk 50, a short wire 51, con-- -necting same with the contact-pin 37, the" cup 27, throu 1 the liquid, the'eup 31, the pin 40, through the wire 39 and battery 42 tothe pin'46.

Instead of the coils of felt or similar, material it is obvious that any suitable filtering means maybe used ,such as-sand or charcoal, Other forms of permit of'a more rapid flow of the liquid. I

' With the openin of the supply-valve and the closing of the e ectric circuit the current flows through the various metallic connections and from one of the cups 27 and 31 to the other through the liquid in the cup 31', causin or anic substances to be attracted towar eac other and cease to be held insuspension in the water and to be precipitated and arrested by the filtering means while the purified and filtered wateripasses oii through the perforationsi'h the cup 31 for When itis-desired to clean consumption. the filter, the nuts 17 are unscrewed and the plate 14-rem'oved.
